The map on their Facebook page isn't very precise, but this is the space on the 5PTS strip formerly occupied by Nest Living, in the Theatre Building to the right of Tasti-D-Lite. They've been doing interior buildout for months now. It's a small space, but they've installed a full lunch counter across half the dining room, with table seating on the left. I expect it will be similar to Gina's Delicatessen around the corner.
